对传统的Ｈｏｐｋｉｎｓｏｎ 压杆实验装置进行了改进和完善，除了用于材料的动态压缩实验以外，能够进行动态拉伸、动态剪切、裂纹扩展速度测定、动态断裂韧性测试等．本文介绍了几种实验方法的基本原理，并给出了实验结果．
The traditional Hopkinson pressure bar experimental device has been improved and perfected. In addition to the dynamic compression experiments for materials, it can perform dynamic tensile test, dynamic shear test, crack propagation test and dynamic fracture toughness test. This article describes the basic principles of several experimental methods, and gives the experimental results.
